NSCLC cell-derived exosomal circATP9A induces macrophages M2 polarization. Notes: A Representative images of A549 cells after incubation with PKH26-labeled NSCLC-EVs; B Co-cultivation mode diagram; C Flow cytometric analysis of the expressions of CD206/HLA-DR in macrophages treated with exosomes with different circATP9A levels. Numerical values denote the relative fluorescence intensity; D The proliferation ability of A549 cells was assessed by CCK8 assay [(EXO and co-cultured with T)P-1 (Mφ)]; E The invasion ability of A549 cells was assessed by CCK8 assay [(EXO and co-cultured with T)P-1 (Mφ)]; F A schematic model of this study
